I have imported two interpreted seismic reflection sections into RockWorks 17, and see the same faults/fracture zones on both sections. I think the sections are not perpendicular to the faults, so can only calculate apparent dip. Then goal is to measure the fracture zone's modeled dip, dip direction, and estimate length for multiple features to support integrated fracture trace study and groundwater monitoring drilling program. What work flow or process would you recommend for doing this in RockWorks?
Thank you very much in advance,

I built a RW2D contour map with data types represented by 4 different symbols (RW17, Feb 2016 build). I built a symbol index table using the same point numbers & colors. When I insert the index legend, the legend is empty though I have selected the only symbol index table in the project (I am unable to deselect the color option, but the color table title is None).
Suggestions?
Happy Holidays,

Tom,
I will soon be importing several profiles to rectify, digitize surfaces and contacts, and then turn the picks into contour maps. Does RW17 use the same approach for generating XYZ coordinates as the 2010 version, or is an alternate approach?
Thank you in advance for your time, and have a great week,

What is the best/a good way to address non-detects so follow-on contour plots do not misrepresent the T-data set?
I am preparing to import lab chemistry results from a long term monitoring program to generate contaminant contour maps. Most of our results are non-detects, several are J-values below the detection limit, and some wells were not sampled due to lack of water (water levels are the only data collected). Fields for missed samples can be left blank. Entering a zero is misleading for non-dected results, and will bias contour plots. I have toyed with the idea of entering the detection limit (variable across sample sets and dates), then applying a lower bound to the data countours at the map-making stage. What other work arounds have the community used?
Thank you in advance for your time,

I am working with five wells worth of televiewer classified into 11 different catagories (transmissive fractures, contacts, fracture zones, etc [1,570+ features]), and would like to build rose and stereonet maps for each of the catagories. Should I build a Datasheet file for each of the catagories using the same format as that for the fractures tab of the Excel Import File?
Many Thanks in advance for the assistance,

What is the most efficient way to add overburden-bedrock outcrop boundaries to RockWorks for 3D modeling?
I am starting a project at a site where bedrock topography changes create isolated oucrop poking through the glacial till. The goal is to model the till thickness and bedrock topography using available well data and available outcrops. I have scanned outcrop maps and some LiDAR innterpretations done in ArcGIS (2D shape files). Before I commit to adding hundreds of ghost borings, is there another way to get the contact boundary data into RockWorks?
Thanks in advance for your time!

Thank you Tom.
If our GIS shop has the ArcGIS LiDAR module, I will see if I can get the XYZ boundaries through that module. If this is successful, should I then use the Utilities Grid | Filters | Limit menu command to combine surface and subsurface grids?
If this is a bust, I will try the full approach above and let you know how I fare.
